Description:
------------
there will be a error Warning: imagegif(): Invalid filename '' occur when the 2nd argument of imagegif filename=='' and the 3rd argument are not set,we might find it during the function GD::_generate in GD.php. imagejpeg,imagepng have the same problem.(but in this GD::_generate,the imagejpeg use three parameters when $filename=='',so when a image is of the jpg type,there is no error occur)

Test script:
---------------
$gd=new Image_Transform_Driver_GD;
$gd->load('1.gif');//$gd->load('1.png');
$gd->display();

Expected result:
----------------
display a image

Actual result:
--------------
display none,just headering a image content-type
